This invention relates to, so termed, metal trim, a sheet or strip metal finishing strip that is used around openings in a building, and is also used in place of a wood mop-board or base. The metal trim is used around openings instead of Wood casings and serves to finish oil the edge of the plaster. Metal trim is also used exteriorly around the margins of openings to finish off the edges of stucco and other cementitious material used for exterior finish.

One of the important objects of the invention is to make provision for holding the metal trim under tension against the finished jamb of an opening.

Another object is to provide a groove serving as a line of demarcation in painting, and

also serving to receive the edge or" wall paper or other wall covering, thus to practically conceal that edge of the wall covering that lies adjacent to an opening or adjacent to the edge of the plaster or stucco, wherever such edge may be.

Another object of the invention is to provide a construction that will insure against breaking or cracking of the plaster away from the metal trim.

Another object is to insure against the plaster forming a feather-edge, such feather-edge easily chipping or flaking OE and thus spoiling the appearance of the interior or exterior finish.

Another object is to provide a construction that will reinforce the exposed edge of the metal trim.

Another object is to provide a construction of metal trim for flush bases that will be securely held in place without the necessity of backing them up with plaster, wood, or other material. 7 I

Another object is to make provision for jointing the metal trim at the corner of an opening in such manner as to insure against the joint opening up or, in other words, to insure that one strip of metal trim does not pull away from another strip with which it forms a corner.

Other objects and advantages will appear in the subjoined detailed description;

Figure 8 is an enlarged view of the horizontal strip of; metal trim used in the joint shown in Figures 2 and 7 v F irst referring to Figs. 1 and 2 of the drawings, a rough stud is indicated-at A and a finished jamb at B. The exterior cementitious finish or stucco is indicated at C and the interior plaster at D; The metal trim, indicated in general at 9, is secured by nails 10, or their equivalents, to the rough stud A and by nails 11, or their equivalents, to the finished j amb B. In this instance, the metal trim 9 is shown exteriorly to finish the edge of the stucco C, and, also, interiorly to finish the edge of the plaster D. The metal trims for exterior and interiorfinish are practicall y alike, though they may be somewhat diferent in size and, accordingly, a description of one will suflice for both.

The metal trim comprises a base portion or ur flange 12, a portion 13 extending outwardly from the portion 12 and returned upon said portion 12. In this instance, the portion 13 is curved, though it is to be understood that itmay be of any desired shape. The portion 13 terminates in a bead 14 that projects to.- ward the portion 12. This head'l t, preferably, is V-shaped, though it may be of other shape if desired. The bead 14 at its open side on the outer face of the portion 13 and,

thus, produces an exterior groove 15 that extends longitudinally of the metal trim, and the opposite walls 16, 17 of the bead 14 are of substantially the same height, so that when the plasterer applies the plaster D he is enabled to readily finish the plaster oif flush with the outer edge of the bead wall 16.

The head 14 not only defines the groove 15, but it serves to stiflen the metal trim at the exposed margin of said trim. The wall 16 0f the head 14 forms an angle with the outer face of the plaster. In this instance, the angle is an obtuse one. Because of the outer face of the plaster being at an angle to the bead wall 16, said plaster will be of a mate rial thickness adjacent the wall 16, Whereas, if the metal trim portion 13 terminated in a plane coinciding with the plane of the outer face of the plaster, the said plaster would tend to feather adjacent to the metal trim, and the edge of the plaster would flake and break away from the metal trim, especially if the metal trim were subjected to knocks, as is very liable to happen.

E indicates a wall covering such, for example, as Sanitas, and it is readily seen that the edge of the wall coveringthat is applied to the wall nextto the metal trim is turned into the groove so as to produce a neat finish along this line. It is readily seen that, if a coat of paint constituted the wall cover E, the painter, in applying the paint, would be enabled to readily follow the line of demarcation between the coat of paint on the wall, which may be of one color, and the coat of paint on the metal trim, which may be of another color, since the painter carries the color of the wall paint into the groove 15. The actual line of demarcation between the paint of the wall covering and the paint of the meta] trim may be irregular, but because of it lying within the recess 15, it does not readily appear to an observer.

Of course, the metal trim surrounding an opening in a wall is applied in separate strips, and two of these strips are indicated at 18, 19 in Fig. 2. Ordinarily, strips of metal trim surrounding an opening are jointed by a miter joint and the joint is coped. When the joint is made in that manner, it readily opens up by unequal strains upon the different strips, as would be produced, for example, by earthquakes or unequal settling of different portions of the structure. I provide a joint construction, between the strips 18, 19, that remains tight because a pull on either of the stri s will be transmitted to the other strip. T is joint is constructed as follows: The portion 12 of the strip 18 projects beyond the portion 13, and this projecting portion is provided with a hole 20 to receive a nail, not shown.

The end of the portion 13 is notched at 21 and communicating with said notch is a kerf 22. The notch 21 and kerf 22, together de- .portion of its length, the edge 24 overlaps the portion 13 of the strip 18, and for another portion said edge 24 abuts the angular face of the notch 21. In other words, that portion of the edge 24 that projects beyond the tongue .23, abuts the angular wall 25 of the notch 21.

This produces a neat joint that requires no soldering, since a nail, or equivalent fastening device, is driven through the hole 20 and through the strip 19, thus firmly securing the strips 18, 19 together.

Now, referring more particularly to Figs. 3 to 5 and 7, the elements that functionally correspond to those hereinbefore described are indicated by the same reference characters, with the'addition ofthe suflix a. This form of the invention is used, for example, in finishing off the-lower portions of the walls of a room adjacent to the floor. In this intance, there projects downwardly from the bent-over portion 13a a vertical portion 26 which has its lower portion curved outwardly, at 261. Projecting inwardly from the portion 261 is a horizontal member 27 and projecting downwardly from the horizontal member 27 is a vertical flange 28.

Projecting inwardly from the portion 26 at an acute angle is the returned or bent-over portion 13a, and projecting upwardly from the portion 13a is the vertical base portion 12a. The distance from the outer face of the base portion 12a to the outer face of the portion 26 is equal to the thickness of the plaster Da. 7 The flange 28 is secured to the floor by suit able clips which are indicated, in general, at 31, and which are formed of sheet or strip metal. These clips are slipped onto one end of the base so as to secure said base, at intervals to the floor. Each of these clips is constructed as follows: There is a horizontal base portion 32, and projecting upwardly therefrom is a vertical member 33 and the strip is doubled back on itself at 34 and again at 35 so as to form a slot 36 between the portions 34, 35. The portions 34, 35 and 36 are in vertical relation with the base portion 3a. Projecting approximately horizontally from the portion 35 is a flange 37 which is substantially parallel to the base portion 32 and overhangs said base portion. When the clip is slipped onto the metal rim or flush base, indicated in general by the character 38, the flange 28 of said base is positioned between the clip portions 34, 35 and the flange 37 of the clip overlies the horizontal member 27. Thus, in Fig. 3, the clip portion 34 prevents movement of the metal trim base to the right, and the clip portion 35 prevents movement thereof to the left, while the clip flange 37 prevents nesaeeo separation of the horizontal member from the floor whichis indicated at 39.

The clips 31 are secured by nails 40, or their equivalents, to the rough floorv 41 and the finish cement slab 39is then formed so that the upper face thereof is flush'with the under face of the metal trimportion 27-. The clips 31 are placed at suitable intervals, as indicatedin Fig. 4:.

It will be seen that when the metal trim base 38 is secured in place, as illustrated in Fig. 3, it is unnecessary to back it up with plaster or other material, thus materially reducing the cost of construction where a metal mop base of this description is employed.

One of the important feaures of the invention is the construction that insures close fit of the metal trim along the line whereit lies adjacent to the window or door jambs and sub-sills of window openings, preventing water from running between the metal strip and the jambs or sub-sills. For this purpose the base portion 12 has a ridged construction, the apex of the ridge being indicated at 42. The apex projects outwardly toward the portion 13 and the flange 12 slopes inwardly away from the apex to where it joins the portion 13. In its natural condition the base portion 12 slopes outwardly from its margin toward the portion 18, thence inwardly away from said portion 13, so that when the base portion 12 is secured to the supporting member, in this instance the finished jamb B, the line of junction of the base portion 12 and returned or bent-over member 13 will be drawn snugly against said supporting memher.

It will be noted that the fastening device 11 is positioned approximately at the apex 42 of the ridge so as to produce the requisite tension when said fastening device is driven into the supporting member.
